Conditions
Summary
The goal of this clinical trial is to learn if an exercise protocol can improve temporomandibular pain, jaw function and muscle mechanical properties in individuals with Temporomandibular Disorders (TMD). This study focuses on patients who are already receiving occlusal splint therapy. The main question it aims to answer is: How does the addition of an exercise protocol to occlusal splint therapy affect temporomandibular pain, jaw function and muscle mechanical properties of the masticatory and neck muscles? Researchers will compare the group receiving both occlusal splint therapy and the exercise protocol to a group only occlusal splint therapy to see if the combined approach is more effective. Participants will: * Undergo an initial assessment of the Jaw Functional Limitation Scale-20 (JLFS-20), Craniofacial Pain and Disability Inventory (CF-PDI), Graded Chronic Pain Scale Version 2.0 (GCPS-2.0), jaw range of motion, pain pressure threshold and muscle mechanical properties. * Receive occlusal splint therapy as a part of their treatment. * Perform a structured exercise protocol (only 1 group) * Attend follow up sessions at the 4th week to monitor changes in all initial assessment parameters.

Interventions
Participants will be provided with custom-made hard acrylic occlusal splints. They will be instructed to wear the appliance every night during sleep for a period of four consecutive weeks. A licensed dentist will manage the delivery and occlusal adjustment of the splints to ensure they were correctly seated and well-tolerated by the subjects. Both groups will receive a occlusal splint to be worn every night.
Participants will perform the Rocabado 6x6 exercise protocol, which consists of six specific movements designed to restore proper tongue position, improve jaw mobility, and stabilize the craniomandibular relationship. Each exercise will be performed 6 times per session, 6 times a day. The protocol includes: Rest position of the tongue, shoulder posture, stabilized head flexion, axial extension of the neck, control of TMJ rotation and rhythmic stabilization technique. The program consists of performing 6 specific exercises, 6 times per day with 6 repetitions each, for 4 weeks.
